Sorry for resurrecting a dead thread, but, I'm having the exact same problem, anyone ever figure this out?

Thanks.

 

I moved your post to a new thread to prevent confusion.

Please post brand, model and serial numbers from your mower and engine. Please describe, in your words, what the problem is.

 

I don't know why this became unhinged from the original thread it was on, but since this doesn't make much sense now, I will say that originally this post was in reply to a thread about a husqvarna that had a shaking deck when the blades were turned on.

This is most commonly caused by a burned spot somewhere on the blade belt. I sus
pect that is your problem.

 

Oh, I was typing at the same time as Airman. I see now.
